CAUTION:
Do not touch the spark plug or plug cap if the engine is
running (high voltage).

The spark plug must be replaced in case of damage to the
insulator, electrode erosion (burn) or if the electrodes are very
dirty or oily.

Unscrew 3 screws (11) and remove the upper half of the
muffler (12).
Note: For saw models with catalytic converters (EA3500S,
EA3501S), remove the converter along with the upper muffler
half.

If they are loose, tighten by hand (Caution: do not over-
tighten).
